Abstract

Severely skewed sex ratios in zebrafish stocks can pose significant hurdles for line propagation and sperm cryopreservation. To overcome female-biased sex ratios in stocks derived from imported sperm samples, the Zebrafish International Resource Center has implemented routine supplementation of larval food with 17α-methyltestosterone to skew gonadal sex differentiation toward masculinization. Resulting stocks averaged 80% males.

用17α-甲基睾酮诱导斑马鱼种群雄性化的简单方法

斑马鱼种群的性别比例严重失衡，可能对种群繁殖和精子冷冻保存造成重大障碍。为了克服从进口精子样本中获得的种群性别比例偏雌的问题，斑马鱼国际资源中心在幼虫食物中添加了17α-甲基睾酮，以使性腺性别分化向雄性化倾斜。由此产生的种群平均80%为雄性。

期刊介绍： Zebrafish is the only peer-reviewed journal dedicated to the central role of zebrafish and other aquarium species as models for the study of vertebrate development, evolution, toxicology, and human disease. Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies. While genetically more distant from humans, the vertebrate zebrafish nevertheless has comparable organs and tissues, such as heart, kidney, pancreas, bones, and cartilage. Zebrafish introduced the new section TechnoFish, which highlights these innovations for the general zebrafish community. TechnoFish features two types of articles: TechnoFish Previews: Important, generally useful technical advances or valuable transgenic lines TechnoFish Methods: Brief descriptions of new methods, reagents, or transgenic lines that will be of widespread use in the zebrafish community Zebrafish coverage includes: Comparative genomics and evolution Molecular/cellular mechanisms of cell growth Genetic analysis of embryogenesis and disease Toxicological and infectious disease models Models for neurological disorders and aging New methods, tools, and experimental approaches Zebrafish also includes research with other aquarium species such as medaka, Fugu, and Xiphophorus.
